CLA MPlNG-JAW FOR V ISES.

SPECIFICATION forming part of Letters Patent No. 569,057, dated October6, 1896. Application filed March 23, 1896. Serial No- 584,413. (Nomodel.)

To all whom it may cancer-7t.-

Be it. known that 1, ROBERT MICHAEL REILLY, a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Clamping-Jaws for Vises, of whichthe following is a specification.

This invention relates to pipe and rod vises, and particularly toclamping-jaws adapted to be held between the jaws of ordinary vises.

The object of the invention is to provide jaws having graduated groovesor corrugations in their face at angles to each other, said grooves orcorrugations being of such curvature or shape that a pipe is clenched orclamped by and between the points of intersection of the grooves andflat portions of the jaws.

A further object of the invention is to provide a weighted anchor orcounterweight for the jaws, to which the latter are pivoted, to restupon the vise-jaws of any size or shape and leave the major portion, orthe grooves in which a pipe is to be clamped, projecting above and clearof the vise-jaws.

Other objects and advantages occurring from the special construction andarrangement will be revealed in the specification to follow.

In the accompanying drawings, forming part of this application, Figure 1is an end elevation of my improved clamps applied to a vise and holdinga pipe. Fig. 2 is a face view of one of the clamping-jaws. Fig. 3 is atop view of one of the clamping-jaws and its pivoted anchor orcounterweight. Fig. 4 is a modification.

The same numeral references denote the same parts. throughout theseveral figures of the drawings.

All pipe-clamps heretofore known used in connection with smiths visesset down between the vise-jaws and the pipe to be operated upon has tobe extended through or be tween the vise, which is a great disadvantage,owing to the interference of the work-bench, table, or wall to which thevise is attached, and where there are two or more pipes joined togetherit is impossible to hold them in position to be treated withoutdisjoining them. It is to overcome these objections and disadvantagesthat this invention is designed.

- The vise-jaws 1 are of ordinary construction and may be of any shape.The counterweights or anchors 2 are made of such shape as to rest uponvise-jaws of any form or size without altering or changing the size orshape of the said anchors. Thefree end of the anchor 2 has an enlargedportion 3 with a shoulder 4, which maybe used for temporarily holding afile, chisel, or other tool while the position of the pipe 5 is beingchanged. The body of the anchor is curved or in the shape of an arcof acircle, and has an ear or lug 6 formed at right angles to the curvedbody flush with the inner edge of the latter, said ear or lug having anaperture through which extends a pivot '1'.

The jaw 8 is pivoted about its center upon the pivot 7 and is free to berevolved or turned at any desired angle with at least one of thegraduated grooves or corrugations 9 and 10 clear above the vise-jaws andalso above and out of interference with the anchorsthat is, the pivotsof the clamping-jaws are always above the vise-jaws and not between thelatter, and thereby allow a pipe to be held by the elevated grooves overthe vise-jaws and above the vise-bench.

The grooves 9 are graduated in size and extend lengthwise the face ofthe clampingjaws, and the grooves 10 are likewise graduated and areformed crosswise the jaw-face at right angles to the grooves 9. Allthese grooves are made deeper than usual, so that their face width isless than their depth, and atthe juncture of each groove and'the flatface of the clamping-jaw is formed a pipecontact edge or point 11. Thuswhen a pipe is clamped it is not mutilated'or defaced by coming incontact with the groove'surfaces, but is securely held pinched betweenthe said edges.

Referring to the-modification shown by Fig. 4: of the drawings, the jawis identical with those already described, except the widthof the jaw isincreased and provided with diagonal grooves 12, of the same characteras the grooves hereinbefore described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an attachment for Vises, the combination of the jaws havinggraduated grooves with counterweights pivoted to said jaws and adaptedto anchor the jaws with certain of theigro'oves above the vise,substantially as set forth.

5 2. In an attachment for vises, the combination of the jaws havinggrooves forming clamping-points at the intersection of the grooves andthe face of the clamps, with the connterweights pivoted to the center ofthe 10 jaws, and adapted to anchor the latter to a vise with the pivotabove the vise-jaws substantiallyas and for the purpose set forth.

3. The combination with the jaws having graduated grooves at rightangles to each I 5 other, of the anchors pivoted centrally to the jaws,and having an enlarged free-end portion provided with ashouldersubstantially as and for the purpose set forth.

4. In a pipe-clamp attachment for smiths vises, the combination of thejaws having 20 grooves at right angles to each other and diagonalcorner-grooves, with anchors having one end pivoted to the jaws and theother end left free and provided with an enlarged portion to Weight theclamps in operative po- 25 sition to a vise, as set forth.

In witness whereof I hereunto set my hand in the presence of twowitnesses.
